气体软氮化是无产阶级文化大革命以来试验成功的一项化学热处理新工艺。它具有设备简单,操作简便,适用范围广等优点。该工艺不仅能提高零件的耐磨损、耐疲劳、抗咬合、抗擦伤的性能,而且还具有不受钢种的限制,处理时间短,工艺温度低,零件变形小等特点。实践证明,气体软氮化新工艺为提高产品质量和以普通钢材代用高级合金钢开辟了一条新的途径。发展和推广应用这项新工艺具有重要意义。几年来,气体软氮化工艺在我国得到了迅速发展,各地根据具体的资源和设备条件,积极开展科学实验,已经取得了不少成绩,目前应用的气体软氮化工艺可归
Gas nitrocarburizing is a successful chemical heat treatment process since the Great Proletarian Cultural Revolution. It has the advantages of simple equipment, easy operation and wide application range. The process can not only improve the parts wear resistance, fatigue resistance, anti-bite, anti-galling performance, but also has not limited by the steel species, the treatment time is short, the process temperature is low, small parts deformation and so on. Practice has proved that the gas nitrocarburizing new technology to improve product quality and substitute common high-grade steel alloy steel has opened up a new way. Develop and promote the application of this new technology is of great significance. In recent years, the gas nitrocarburizing process has been rapidly developed in our country. Various scientific experiments have been actively carried out in various places according to the specific resources and equipment conditions. At present, the gas nitrocarburizing process applied has been achieved
